Major depressive episode (MDE) and suicidal ideation (SI) associated with history of foster care placement (HxFCP), and mediating effects of psychosocial and socioeconomic factors through which placement may confer psychiatric risks in the years subsequent to emancipation were examined in a national sample of 7534 Métis. More than one third of emancipated respondents reported past year MDE, a prevalence rate nearly 50% higher than the rate of MDE among Métis respondents without a history of placement in foster care. The 25% lifetime prevalence rate of SI in the emancipated group was more than twice the rate observed in the non-fostered group. Direct effects of HxFCP on post placement MDE and SI were significant in multivariate logistic regression analyses, even when effects of childhood predispositional risk factors were controlled statistically. Emancipated individuals were unduly affected by psychosocial and socioeconomic disadvantages signifying pathways that linked foster care placement history and psychiatric status. Main mediators of the effects demonstrated using effect decomposition procedures were self-esteem, income, and community adversity. The findings warrant consideration of foster care history in clarifying the complex etiologies of suicidal ideation and major depressive episode in the Métis population and risk factors ensuing in the intervening years as integral to the process linking placement to long-term psychiatric outcomes.
在一个由 7534 名梅蒂斯人组成的全国性样本中,研究了与寄养经历(HxFCP)相关的重度抑郁发作(MDE)和自杀意念(SI),以及通过这些安置可能在解放后随后几年带来精神风险的社会心理和社会经济因素的中介作用。超过三分之一的解放后受访者报告了过去一年的 MDE,其患病率几乎比没有寄养经历的梅蒂斯受访者的 MDE 率高出 50%。在解放组中,SI 的终身患病率为 25%,是未受抚养组的两倍多。即使在统计学上控制了儿童倾向性风险因素的影响,HxFCP 对放置后 MDE 和 SI 的直接影响在多变量逻辑回归分析中仍然显著。解放后的个体受到社会心理和社会经济劣势的过度影响,这些劣势表明了将寄养经历与精神状态联系起来的途径。使用效应分解程序显示的主要中介因素是自尊、收入和社区逆境。这些发现值得考虑寄养历史,以阐明梅蒂斯人群中自杀意念和重度抑郁发作的复杂病因,以及在安置到长期精神结果的过程中,干预期间出现的风险因素。
